Variable Fillet?

[Eric S.]

Hello all

 

Fist off let me try to explain what I am doing. I am making a mold half for a T shape 5" dia. pipe (looks like a block that a 5"dia ballnose cutter ran through in a T shape 2.5" deep) . I want to fillet the solid model with a variable radius where the two diameters intersect (.27R at the top to .5R at the deepest point), I keep getting the error "Blend Creation Failed. Probable cause: Blend overflow removes adjacent face or edge". Any ideas on how to do this?

Eric,

I tried, and it worked fine for me ??

Thanks for the help.

 

 

This is what I have been trying:

 

1. Solids

2. Fillet

3. Edges Y the rest N

4. Select the 2 edges that form a curved v shape

5. Done

6. Fillet Parameters window:

Variable Radius...Smooth

Overflow:Default

Edit window:

Edge 1, 1st vertex .27rad. 2nd vertex .5rad.

Edge 2, 1st vertex .27rad. 2nd vertex .5rad.

 

7. Click OK

8. Blend Creation FAILED!

9. go have a beer.

10. Come back...Still failed

 

??????????

Eric,

Try each edge Individually. If that fails, did you make or import the model ?

Here is a screenshot of the part Eric is trying to fillet.

Try a different overflow ?

 

or...just have another beer and do it later.

hi Jg

 

I made the model and tried to do one edge at a time but still fails.

 

Thanks for the pic Phil.

Much easier

[JG]

can you upload the file? or can I email you mine?

 

thanks,

Eric,

you got mail.

[Eric S.]

Thanks

 

Yours model works fine even when I try and redo it. I think the problem is the way I made my model. I revolved the cutouts because there are actually dia changes at the ends that I did not add yet (I figured this varying radius was going to give me trouble so I'm getting a head start on it). Maybe I'll have to extude my model for it to work.

 

I'll mail you my model if you like to give it a try.

Have you tried to cycle it and also add a dynmaic point in which you might be able to g ofrom 2 to .26 then to .5 I have done this on many parts and had great success.

Eric,

It is on its way back, see if that is what you wanted.

??? I get the error just opening the file???

When it opens there are no fillets.

Now this is just snowballing now. lol

 

FYI I'm using Mill V9.0SP1

aahhh, 9.1 sp something , mr , mu, etc

your model worked fine in my system, maybe its something with the Pairofsolid colonel.

Could this be a maintenance issue maybe? Our tech guy is a little backed up

[Eric S.]

MR fixed the issue!

 

Now everything seems to be working the way it should.

 

Thank you very much for your help!
